Hi guys,
I have 2000 GMC Jimmy with a weird recent starting problem. When it's cold it'll start up. When I run it for about 20 mins or more and shut it off and then start it again within a min or two it will start. However if I run it for the same 20 mins or so and shut it off and start it again in about 10-12 mins it won't start.I have to leave it until the engine cools off, like for an hour, then it'll start up again. It does like this (I took this link from one of the guys here, thank you)

Last night I drove from work to supermarket which takes about 25 mins. I spent about 15 mins inside and when I came out and tried to start it it wouldn't start. I had to sit in it for an hour to let it cool off then it started. thanks to the fall weather it started in about an hour. In summer I don't know how long it'll take. It makes like it'll start but it doesn't. I changed starter, battery,wires that go to spark plugs. Mechanic ran OBD test and couldn't find anything wrong. He checked spark plugs and said they were ok.
Can anyone advise, please? Thank you very much!
